To allV whomn tina/y1 concern Beit known ythat I, JOHN jBAoBnLDER, of Norwich, in `the county of New London and State of Connecticut,"haveinvented certain new and",y useful Improvements in' Machinery for-,Coveringwand Layingv Cord, and IV do hereby declarethat" the following is a full', clear, and exaetdescription thereof, reference being had tof, the accompanying' drawings, making a part of 'this specification, inwhichfhigurell, Plate 1, is Ya perspective view of theimproved machine complete. Fig. l2, Plate 1, is a section ,throughy thenachine, takenin thehorizontal plane indicated by linen; a: in`

Fig. 4 of'PlatewZ.` iFig. 3, Plate 1, isa section takenthrough the machine in the horizontal plane indicated by liney y in Fig. 4 ofPlate 2.` i,Figi 4 Plate 2,is a vertical ,sectiontaken throug'hlthe center of the machinei f VSimilar lettersl of reference indicate -correspending partsjn the .several lgur'es'. p

l This invention relates,l to `certain new and useful improvements on machinery whichv is designed for covering twisted strands of comparatively coarse and cheapthreadswith silk or4 othei` more expensivel threads, in rthe'nianu'- factureA of cord whichy is usedA for hanging pictureLframes', and for other purposes, thereby producing aA much cheaper articlethan could be made by the use of an expensive material a one.

Ehepaare or my invention consists inL the y employment,.inl a" machine which4 will cover each twisted ,strand with silk or other suitable covering material, of certaininech'anism which will lay the covering material upon-the twisted strandsl ina 4converse directionV to the twist given to each one of said strands, thereby producing co'rd which will be smoother1 and more compact than cord produced in any other manner, aswill behereinafter explained.

To enable others skilled in the art to underl stand my invention, I will `describe its construction and operation.

The frame of themachine which I am about to describe may be constructed in any suit` able manner which will adapt it for receiving and supporting the cording mechanism. I prefer to construct this frame of several horizontal disks or circular plates, AA1 A2 A3 A4 A5, secured in a suitable manner to upright posts or rods B B B, which are arranged con-y `tancesl apart.

centrically around the centers of' thedisks at'equal distances apart, as shown' in the' drawings. Y 'i Upon the bed-plate or bottom disk A is stepped a vertical rod, C, which passes up through the centers'of the two disks'A1 A?, and carries two spur-wheels up'onit,` which rotate in the direction indicated by the arrows in Fig. 1'. Thefbevel-spur wheel a is keyed ori the' rod C nea'r itsflower'extremity, and engages jwith a bevelspur wheel, a', upon a horizontal drivingLsha'ft,` b; This shaft bis v supported-Qin blocks b1 h1 upon the bed-plate A, and carries a beltldrum, b2,.upon it outsidey of said blocks. y' l 1 I The bevel-spur wheel a "also engages' with a bevellsp'ur Wheel, c, which is fast upona collar ortube', c' ,l through which latter the rod C passesV freely. This collar passesfreely throughjthecenterof thefdisk` A1,'and. ear-riGS uponits upper end:l a'l .pinion spur-wheel, d,

whichis` caused: to rotate in a' direction opposite tothe' rotation of the rod C,'as indicated by the arrows'in'hig. l.'

Thepinion-wheel d, which is on top' of plate A1, engages withv the teeth' of 'three spurwheels, dlrdd, that areap'plied upon fixed st'udsdz projecting perpendicularly from the top surface of theplate yA1, and arranged equidistant from each other aroundthe-axis of the rodG. Each one ofthe spur-wheelsd1 has a hollow central hub, @,with four Aholes made laterally into it, leading into a central vertical h olcfmade throughits upperend; The holes through the sides' of thel hub e are equal disvided on itstop` surface with four vertical studs, t, arranged opposite the lateral holes `through the hub e, which studs receive spools carrying the threadsl toi. form the strandsof the cord whichY it'.A is designed to"produce'.

Said spoolsor bobbins lare indicated in Figs'.`

35 and 4, and are supported upon'f frictioncushionsto prevent themV from turning too freely.

On top of the plate A2, and keyed to the rod C, is a large spur-wheel, D, the teeth of which engage with pinion spur-wheels f, which are applied to tubular studs g, so as to turn freely around these studs. The studs g are short tubes, which are secured iirmly into holes made through the plate A2,.for the pur- Each' Wheel' d* is" also propose of receiving through them the twisted strands; of thread leading from the lower twisting-wheels d1, as shown in Fig. 4and allowing these twisted strands to be covered with silk or other suitable covering material. The pinion spur-wheels f are secured fast to the bottoms of horizontal rotary disks F F F, and in the centers of these disks. the top surfaces of the disks F, and in the centers thereof, hollow hubs" 71, proj ect, throughwhich the twisted strands pass on their way to the flier. Each one of said disks F carries two studs, h hf, upon which the spools or bobbins 'are placed that carry the covering material. The covering-threads pass from each pair of spools through holes made laterally through the hubs h, .and rthey are wound or laid upon the twisted strands within these hubs as the strands are slowly drawn toward the flier to be twisted into cord. f The twisted andcovered strands are carried fromL the upper ends of the hubs h of plates F over grooved sheaves in pendants G, which are secured to the plate A3,- and from these sheaves the strands 'are carried up through the center of a vertical tube or guide, J which issecured fast ina hole made centrally through the frame-plate A3, as shown in Fig. 4. Directly above the tubeor guide J is another tube,or guide, K, which is secured fast in a hole made centrally through the frame-plate A4,- and which extends a short distance above .the top of this plate. Upon this tube K is a large bevel-spur wheel, L, which turns freely around it, and also a smaller bevel-spur wheel, M, which is secured fast to it-above the wheel L. The wheel L engages witha pinion-wheel, l, upon a shaft, L1, which has its bearings in a block, L2, upon plate A4, and which receives motion from themain shaft b through the medium of a belt, N, as shown in Figs. l and 4. The wheel L carries an upright rectangular frame, P, which is centrally attached to the top plate A5, so that it will turn freely with the said wheel,- and form a flier for laying together the three twisted and covered strands, and producing a cord of these strands. This Hier-frame P carries, near its upper end, a reel spur wheel, s', that engages with the stationary 4 ,bevel-wheel M. As the Hier-frame is rotated in the direction indicated bythe arrow in Fig. 1, thel slack of the cord will be taken up, and =the cord will be wound upon the reel or drum P", from which itcan be removed at pleasure.

From

The iixed tube J, through which the three twisted and; covered strands' of thread, are carried, is constructed with an enlarged head upon its lower end, through which holes are made converging toward and leading into the central hole through this tube. Thus it will be 4seenthat the twisting together of the three twisted and covered strands will be effected above the lower end of the said tube. Motion may be transmitted to the shaft It from the shaft 1' by means of spur-wheels, insteadof the belt, as shown; but it is desirable to transmit motion to the reel or winding-drum shaft by means of a belt, n, for the reason that this belt will slip whenever the cord has wound on the reel or drum to such an extent'. asto take up they manufactured cord faster than the belt travels. `This belt n is, however, always tight enough to turn the reel or drum fast enough to take up the slack cord.

I do not confine my invention to a iiier which carries the taking-up spool ory drum, but intend to employ either the same or any of the well-known fliers and take-up arrangements which may be adapted for use in connection with my invention. y

Withl the arrangementl of take-up drum which I have shown, itis essential that the drum be driven by a band which will slip on its pulleys'as the bulk of cord increases, such band acting always with sufficient friction to turnltheY drum. I y

Having thus described my invention, what I claim as new, and desire to secure by Letters Batent, is-1 1 l. The :ruiter-gears ata c, central shaft C, supports A1 A2, bobbin-gears dl, coveringcord carriersF, guide J, and gears Z L, in combination, and .operating .so that each thread of a 'strand is covered with finishing material, and the several strands thus covered twisted,- the finishing material being laid ina converse direction to the twist vimparted to the respective strands, all substantially as set forth.- l l 2. The shaft b, gears a a, shaft C, sleeve c', and pinions cd, stationary support A1,- geared spool-carrying 'plates d1, support A, gear D, covering-cord carriers F, and guideI J, combined and operating substantially as and fo the purpose set:l forth. 4 y

'3. In` combination with the above, the winding-and-twisting iiier, constructed and operating as described. f
